Overview of greenhouse horticulture in Portugal: technology and environment
Costa, J. M.; Reis, Mário; Palha, M. G.; Passarinho, J. A.; Carvalho, S. M. P.; Almeida, D.; Nunes, L.; Ferreira, M. E.Total greenhouse production area in Portugal is about 3,000 ha with a tendency for expansion, and tomato is the most important greenhouse crop. Protected cultivation in Portugal modernized in recent decades but remains heterogeneous in terms of technology, yields and management. The sector organizational structure and technological trajectory is characterized by increased greenhouse area per grower and higher v...
Circularidade da horticultura protegida
Costa, J. Miguel; Reis, Mário; Silvestre, R.; Ribeiro, H.; Ferreira, M. E.A Economia Circular (EC) consiste numa abordagem estratégica e operacional baseada na redução, reutilização, recuperação e reciclagem de materiais e energia (Comissão Europeia, 2015). A EC potencia o valor e o tempo de vida útil dos produtos, materiais e recursos na economia ao mesmo tempo que valoriza os recursos renováveis e recicláveis, através do conhecimento aprofundado de processos tecnológicos, ambientai...
Gatekeeping African studies: what does “editormetrics” indicate about journal g...
Ferreira, M. E.; Mendonça, S.; Pereira, J.This paper probes the internal governance of research journals by focusing on the editorial boards of leading African studies academic journals. We submit editorships to systematic scrutiny through a number of perspectives: geography, gender, institutional affiliation, research performance, entry/exit, etc. Overall, leading journals in the area of African studies are found to be less inclusive than expected: un...

Quintas, A.; Albuquerque e Castro, J.; Aragão Morais, J.; Bastos Gonçalves, F.; Ferreira, R.; Vasconcelos, L.; Alves, G.; Abreu, R.; Camacho, N.Introdution: Aneurismal disease involving the thoracoabdominal segment adds significant complexity to endovascular aortic repair. Objective: Evaluate institutional experience of a tertiary center in fenestrated and branched aneurysm repair for throracoabdominal or juxtarenal aortic aneurysms Methods: Retrospective analysis of a consecutive series of patients treated by endovascular repair using fenestrate...
ILIAC BRANCH DEVICES TO PRESERVE INTERNAL ILIAC ARTERY IN ANEURISMATIC DISEASE
Quintas, A.; Albuquerque e Castro, J.; Aragão Morais, J.; Bastos Gonçalves, F.; Vasconcelos, L.; Alves, G.; Ferreira, R.; Abreu, R.; Camanho, N.Introdution: Aneurismal disease of the iliac arteries is present in 11 to 43% of abdominal aortic aneurysms. Iliac branched devices (IBDs) enable the preservation of internal iliac arteries minimizing the risk for complications related to its intentional occlusion. Methods: Retrospective analysis of a consecutive series of patients selected for the endovascular repair of aneurysmatic disease using IBD...
Microeconomic and environmental sustainability of Portuguese greenhouse horticu...
Costa, J. M.; Reis, Mário; Passarinho, J. A.; Ferreira, M. E.; Almeida, D. P. F.Estimated total greenhouse production area in Portugal is 3,000 ha. The potential for expansion of the sector exists, but it must minimize undesirable environmental impacts, while taking advantage of related economic benefits. In 2013, greenhouse production represented only 6% of the total commercial vegetable production area but it accounted for about 16% of total production. Moreover, total production value p...
Gatekeeping African studies: A preliminary insight on what do editorial boards ...
Mendonça, S.; Pereira, J.; Ferreira, M. E.Issues of inequality and distribution of different sorts constitute salient aspects in the agenda of development studies. As globalisation unfolds new indicators are needed in order to update the capacity identify, capture, and interpret its dynamics and asymmetries. Notwithstanding the many changes in the world’s socio-economic landscape, Africa, in particular, remains a marginal geographical and cognitive spa...
